PURPOSE:To integrally form a various coupling and a driving power connecting/ disconnecting device by forming a working chamber from a number of rotary members and housing the viscous fluid and engaging a plurality of resisting plates and a casing with each rotary member in connection/disconnection abled state. CONSTITUTION:An outer case 3a is installed onto a ring gear 2 meshed with a drive pinion gear 1, and an inner case 3b is fitted into the outer case 3a. Inside the inner case 3b, a plurality of hubs 4 and 5 are housed in the relative revolution abled state, and a working chamber 7 in which viscous fluid is sealed is formed. Inside the working chamber 7, a plurality of resisting plate 8 and 9 and a spacer 10 are housed, and a plurality of working chambers 11 and 12 are formed. A driving member 17 is fitted into one supporting cylinder part 16a in the inner case 3b, in slidable manners for one driving shaft 6b. While, a fork 20 is fitted into the driving member 17.
